Private classes in Objective C

Question

I would like a pattern for a nested private class in Objective C.

Requirements are:

• class will not be visible/accessible to other classes.

Answer 1

Well you can have "semi-hidden" private methods. You can include an interface file that provides extension methods that is in the implementation file and then just implement the methods declared in there. I was curious about this before and asked a similar question.
